AdonisJs 5- How to insert a validation to a Route like adonis v4?

[dajpes]

Hi,

In AdonisJs 4, you can do something like this:

Route.post("/myRoute", "myController.create").validator("randomValidator");

Can I do something something like that in version 5? and if not how can I use a validation created using:

node ace make:validator CustomCheck

Inside my Controller?

Here's in the doc https://preview.adonisjs.com/guides/http/form-submissions#using-validator-classes

I was very confused during the first contact with the validation documentation. I believe it is because of this const date variable.

I think it would be more clean with an destructuring assignment example:

const { title, body } = await request.validate(PostValidator)

Hey, validations can be done on controllers through the request context

App/Controllers/Http/UsersController.ts

import StoreValidator from 'App/Validators/User/StoreValidator'
import UpdateValidator from 'App/Validators/User/UpdateValidator'

export default class UsersController {
  public async store({ request }: HttpContextContract) {
    const { name, password, isActive } = await request.validate(StoreValidator)

    const user = await User.create({
      name,
      password: password,
      isActive: isActive ?? true,
    })

    return user
  }

  public async update({ request, params }: HttpContextContract) {
    const data = await request.validate(UpdateValidator)

    const user = await User.findOrFail(params.id)

    user.merge(data)
    await user.save()

    return user
  }
}

App/Validators/User/StoreValidator.ts

import { HttpContextContract } from '@ioc:Adonis/Core/HttpContext'
import { schema, rules } from '@ioc:Adonis/Core/Validator'

export default class StoreValidator {
  constructor(private ctx: HttpContextContract) {}

  public schema = schema.create({
    name: schema.string({ escape: true, trim: true }, [rules.minLength(3)]),
    password: schema.string({ escape: true, trim: true }, [rules.minLength(8), rules.confirmed()]),
    isActive: schema.boolean.optional(),
  })

  public cacheKey = this.ctx.routeKey

  public messages = {}
}

Now I understand, the validation won't work if you change the name of the public variable schema for any other.
